INTERNALLY-PACKED WATER-SPACE JOINT FOR CYLINDERS AND MOTOR-BASES.

Specification of Letters Patent.

Patented Nov. 4., 1919.

Application filed November 12,1918. Serial No. 262,244

To all whom it may concern:

Be it known that I, CHARLES M. MOHLER, a citizen of the United States, residing at Hagerstown, in the county of Wayne. and State of Indiana, have invented certain new and useful Improvements in internally- Packed Water-Space Joints for Cylinders and Motor-Bases, of which the following is a specification.

This invention relates to internally packed water space joints for cylinders and motor bases of internal combustion engines.

The invention comprises means for packing the joint between the water space and motor base or crank case, by devices arranged within the water space whereby it is believed thejoint is more eifectively made and requires less attention after it is once made, than is the case with like joints packed from below in the crank case, with which this applicant is acquainted. a

The preferred construction and arrangement of the parts of this invention, and a modification thereof, are set out in the accompanying drawings, of which Figure 1 represents a side view of a block of three cylinders provided with this invention. Fig. 2 is a vertical section on the indirect broken line 22 of Fig. 1, and shows all parts assembled. Fig. 3 is a side view of a block of three cylinders provided with a modified form of this invention. Fig. 4 is a vertical section on the indirect broken line d-4 of Fig. 3, showing all parts as- Fig. 5 is a plan View of the packing band.

Throughout the description and drawings, the same letter is used to refer to-the same part.

Considering the drawings, Figs. 1, 2 and 5, it will be observed that the motor base or crank case A has an opening a in its side through which may be seen the three cylinders B, C, and D, having the common head casting E secured to the upwardly extending walls of the motor base A by the screws '6. This invention is not intended to be limited to the construction of the cylinder head closely, or to the means for securing the same, as those parts may be varied in form as may be the motor base.

Near their lower ends the cylinders are provided with a projecting shoulder F, as best shown in Fig. 2, and this portion F eitends horizontally as a web between the cylinders as best shown in Fig. 1.

The motor base A has, as illustrated in Fig. 2, a horizontal partition G, and the partition has a suitable opening to receive the lower ends, such as the endzf, of the cylinders. Extending around the cylinders, the partition G has a packing seat H, and upon this seat, which is located. within the water space, is arranged the packing band or link 9. The form of the packing g is shown in Fig. 5, and the projecting shoulder or ledge F of the cylinders corresponds to that form. In Fig. 2 it will be seen that the packing occupies the packing seat and the shoulder F is arranged upon the packing, and all are within the water space formed by the upwardly-extending walls of the motor base, those walls being spaced from the cylinders as set forth. The packing g is introduced and positioned through the opening a in the wall of the motor base. Less conveniently, it could be introduced and arranged before the cylinders are placed in position, in

which case the opening a would not be used. In practice the opening a is closed by a cover plate not shown.

Considering Figs. 3 and 4 there will be understood a modification of this invention, comprising the motor base J having the wall opening j. The common cylinder head is marked K, and the securing screws are designated by the letter is. The three cylinders L, M, and N are in View through the opening j.

-The motor base J has the internal horizontal partition 0, which has a suitable opening for the reception of the lower ends, such as the end Z, of the cylinders. The partition 0 has a packing seat or shelf I within the water space, and the band or link of packing Q is arranged upon the seat. The packing Q; has the same form as that shown in Fig. 5 for the packing 9.

As best shown in Fig. at, the presser band or link R rests upon the packing Q within the water space. To press the packing Q, to its seat and thus effectively close the water space joint, a wedge S is employed, and it is forced in between the integral coupling m that connects the cylinders as illustrated in Fig. 3, and the top of the -presser band B. The wedge S may be locked by an adjusting screw 8, if desired, as set out in Fig. 4.

In the operation of this invention as set forth in Figs. 1 and 2, the packing is placed on its seat and the cylinders arranged so that the shoulder F rests upon the packing. Now, when the screws 0 are set up the packing is compressed between the shoulder F and its seat, andthe water space joint made water tight whether hot or cold.

In the operation of this invention as set forth in Figs. 3 and 4, the packing Q, is placed upon its seat around the lower ends of the cylinders, and the presser band B, previously placed around the ends of the cylinders, is lowered upon the packing. The wedges S are then forced inwardly and the packing is compressed upon its seat b y the presser band. All the parts are located int-he water space as previously explained.

Having now described this invention, and explained the mode of its operation, what I claim is 1. In a joint of the character described, the combination with a cylinder block, of a 1110- tor base having walls provided with an opening and extending upwardly and spaced externally from the cylinders whereby a water space is formed about the cylinders, means connecting the heads of the cylinders and the said walls whereby the top of the water space is closed, the said motor base having an internal horizontal partition having an opening constructed to receive the lower ends of the cylinders, the said partition having a packing seat within the water space and extending about the cylinders, packing arranged upon the said seat, and means for clamping the cylinders, packing and motor base together.

2. In a joint of the character described, the combination with a cylinder block having a projecting head, of a motor base having walls provided with an opening and ex tending upwardly and spaced externally from the cylinders whereby a water space is formed about the cylinders, the said motor base having an internal horizontal partition having an opening constructed to receive the lower ends of the cylinders, the said partition having a packing seat within the water space and extending around the cylinders, packing arranged upon the said seat, and means for clamping the said cylinder head upon the said walls thereby closing the top of the water space and clamping the cylinders, packing and motor base together.

.3. In a joint of the character described, the combination of a cylinder block and motor base, one ofthe said parts having walls spaced externally about the cylinders whereby a water space is f0rmed,the said motor base having an internal horizontal partition having an opening constructed to receive the lower ends 01 the cylinders, the said partition having a packing seat located within the water space and extending around the cylinders, packing arranged upon the said seat, and means for clamping the cylinders, packing and motor base together.

4:. In a joint of the character described, the combination with a cylinder block, of a motor base having walls extending upwardly and spaced externally from the cylinders whereby a water space vis formed about the cylinders, means connecting the heads of the cylinders and the said Walls whereby the top of the water space is closed, the said motor base having an internal horizontal partition having an opening constructed to receive the lower ends of the cylinders, the said partition having a packing seat within the water space and extending around the cylinders, packing arranged upon thesaid seat, the said cylinders having a projectingshoulder arranged above the said packing, and means for clamping the cylinder, packing and motor base together.

5. In a joint of the character described, the combination with a cylinder block having a projecting head, of a motor base having walls extending upwardly and spaced externally from the cylinders whereby a water space is formed about the, cylinders, the said motor base having an internal horizontal partition having an opening constructed to receive the lower ends of the cylinders, the said partition having a packing seat within the water space extending around the cylinders, packing arranged upon the said seat, the said cylinders having a projecting shoulder arranged above the said packing, and means for clamping the said cylinder head upon the top of the said walls thereby closing the top of the water space and clamping the cylinders, packing and motor base together.

In testimony whereof I afiix my signature.
